Planning lintel replacement in Wellingborough

Wellingborough has a mix of housing, and lintel replacement needs a slightly different approach in each. Wellingborough is around 8.8 miles from Northampton, and we cover both. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

We survey the opening, arrange the engineer's specification and building control, prop the wall, swap the lintel and rebuild the masonry and plaster around it. Your quote is written and itemised, and it covers matching the bricks and mortar as closely as the existing wall allows.

Key points for your project

  • Diagonal cracks that start at the top corners of a window and step up through the mortar joints are a classic sign of a lintel problem. Movement elsewhere in a house can cause similar cracks, so the cause is confirmed on site before anything is replaced.
  • In cavity walls, a cavity tray and weep vents above the lintel send any water in the cavity back outside. Missing trays are a frequent cause of damp patches above window heads, so they are fitted as part of the replacement.
  • Replacing a structural lintel is generally treated as building work, so approval is in place before it starts. In England, Wales and Northern Ireland that means building control, and in Scotland a building warrant is needed before structural work begins.
  • Older steel lintels and bare steel angles can corrode where water sits on them. Rust takes up more room than the steel it comes from, so a corroding lintel can lift the brick course above it and open up horizontal cracks.
  • The replacement is specified by a structural engineer, who looks at the opening width, the wall construction and what the lintel carries, such as floor joists, a bay roof or a gable. Solid walls and cavity walls usually call for different lintel types.

Four stages, one team

  1. Survey in Wellingborough

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Wellingborough

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Lintel replacement near Wellingborough

Lintel replacement in Wellingborough: your questions

Do you also work near Wellingborough?

Yes. We also cover nearby towns including Rushden, Kettering, Northampton and Corby.

Can I stay at home while the work is done in Wellingborough?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

What type of lintel will be fitted?

The engineer decides, based on the opening width, the wall construction and the load above. Steel lintels are common in cavity walls, while solid walls or wide openings may suit a different type or a steel section. We fit what the specification calls for rather than a one-size option.

Can a lintel be replaced without removing the window?

Often, yes. The brickwork above is propped, the old lintel is taken out and the new one fitted while the frame stays in place under protection. If the frame has been carrying weight because the old lintel sagged, it may need easing or adjusting once the new lintel is in.

Can a timber lintel in an old house be replaced with steel or concrete?

Yes, where the engineer is satisfied it suits the wall. Timber lintels in older solid-walled homes are often swapped for a steel or concrete alternative that will not rot. The engineer considers how the wall is built, and where lime mortar is present the rebuild uses a compatible mortar.
